Improvement in brushes



\ JOHN L. WHITING, OF BOSTON, MASSACHUSETTS.

IMPROVEMENT IN BRUSHES.`

Specification forming part of Letters Patent No. 107.742, datedSeptember 27, 1870.

To all whom it may concern:

Be it known that I, JOHN L. WHITING, of Boston, of the county of Suffolkand 'State of Massachusetts, have invented anew and useful Improvementin Brushes; and I do hereby declare the same to be` fully described inthe following specification and represented in the accompanyingdrawings, of which- Figure lis a side view, and Fig. 2 a lon- Ogitudinal section, of one of my improved brushes. Fig. 4 is an end view,and Fig. 3 a side view, of the conical expander. Fig. 5 is a side viewof the introducer,-77 or device used in inserting the expander in a massof bristles when placed Within a ferrule.

The handle A of the said brush is furnished witha head, a, to receiveaferrule, B. From this head a round, or cylindrical, or prismatic tenon,T, is extended in manner as represented, it being designed to receiveaconical expander, C, which is a frustum of a cone bored axially toreceive and fit upon the tenon.

In the process of making the brush, the mass D of bristles should rst beinserted in the ferrule B a suitable distance, after which theconical'expander should be placed on the tenon b of a tapering orconical ntroducer, E, formed as shown in Fig. 5, the tenon b'beinginserted into the expander at'itssmaller end. The expander having `beenarranged on the introducer, as described, the latter is to be inserted'smaller end foremost into the mass of bristles ferrule, and in or tothe expander, the 'head e entering the ferrule, and the tenon T goinginto the expander. For this purpose cement may be used to conjoin theparts, or they may be fastened together by one or more screws or otherproper devices. The expander may screw directly upon the tenon; or. inother Words, the latter may screw directly 'into the expander.'

I am aware that in making a brush it has been customary to have atapering expander extend from the handle with the base of the expandertoward and fixed to the handle or its head, the same being asrepresented in the United States Patent No. 39,439, dated August 4,1863, and reissued on Decemberl, 1868, such patent having been grantedto me. In the brush shown in such patent the expander is driven into themass of bristles at its upper end, whereas in my present brush theexpander enters the mass at its lower end, or that farthest from theferrule, and is driven up toward and into the ferrule, and 4subsequentlyis fastened to the handle by being xed upon a tenon or projectiontherefrom, as described, the whole operating to very strongly fasten thebristles within the ferrule and to the handle, and the latter to theferrule, the expander serving as a Wedge or dovetail to aid in hold-.ing the bristles Lto the ferrule.

In another application fora patent recently made by me and allowed, theexpander' is represented as inserted and fixed in the han.

dle. Consequently I do not here intend to claim such, having claimed itin such application.

What I herein claim as my present invention is The connection or tenon Twith the expander C, as shown, in combination With vthe handle A, cap orhead a, ferrule B, and bristles D, all as constructed and represented.
